2.HIIT Training: I like 400m sprint repeats the best. Start with 5 to 7 and increase each week. 60 to 90 seconds rest between.

TIP: Don’t do these on the same day as your weight training.

3.Tabata Protocols: I like to use Tabata-style exercises as ‘finishers’ after a weight-training workout. It’s essentially maximum reps of an exercise in 20 seconds followed by a 10-second rest and repeated for a total of eight rounds (4 minutes or 2:40 of actual work).
